I very rarely use fancy gimmicky features in the Mac OS, let alone Apps from the Apple Store. It seems to be most beneficial on a Mac Book or ipad. But how about Mac Pro users? I really don't see a use for having safari go full screen on a 30" display. I use Gmail, so the new mail flare wouldn't suit me. And gestures on a desktop? How about users trying to get real work done that are not dicking around with family photos and slideshows? I'm using Photoshop, and Premiere Pro on a daily basis. Other then the flashy features of the Lion, are there any performance enhancements that lie beneath?
